Mapalga advice : Remember to clean the Coffee group with cold water at least once a week, and lubricate the coffee group every 500 cafes.

If you use hot water during cleaning, the fat will dissolve, so it will be necessary to grease the parts in motion more often.

in summary :

take a Gaggia fat tube to lubricate the coffee group. Do not use domestic oil, margarine, or even industrial lubricants, they are not qualified for this use. Gaggia fat is of quality for food contact and lubrication for this
mechanism.
